This commit removes the unnecessary layer provided by soc_info.[hc].
It was providing an abstraction which only was resulting in extra
function calls without any added value as the returned constants are
well identified and could be used directly. More importantly, and this
is the actual selling point in my opinion, this extra indirection was
preventing the compiler from detecting array overflows.

Add definitions for the GPIO pins on Panther Lake SoC,
as well as GPIO IRQ routing information and defines for ACPI ASL.
For now, add the following GPIO communities and GPIO groups:
Comm. 0: GPP_V, GPP_C
Comm. 1: GPP_F, GPP_E
Comm. 3: CPUJTAG, GPP_H, GPP_A, VGPIO3
Comm. 4: GPP_S
Comm. 5: GPP_B, GPP_D, VGPIO
ref doc:
- PT EDS vol2
- Panther Lake H GPIO Implementation Summary (#817954)

TEST=Verify on Intel Silicon platform for PTL using google/fatcat
mainboard. Note that these GPIO changes cannot be verified along as
they are merely data structure and defines for the SOC. With the
GPIO ASL, we should see the following GPIO instances under
/sys/bus/acpi/devices when booting to OS:
INTC10BC:00/ INTC10BC:01/ INTC10BC:02/ INTC10BC:03/ INTC10BC:04/
